STEM AT ITS BEST! Bring the excitement of hands-on learning to your next simple machines unit. As part of a series, the K'NEX Education Intro to Simple Machines: Wheels & Axles and Inclined Planes set is designed to introduce students to the scientific concepts associated with two types of Simple Machines - wheels and axles, and inclined planes. Students build, investigate, and evaluate scientific principles in action. The Teacher's Guide, used in conjunction with the K'NEX materials and individual Student Journals, provides the information and resources needed to build students' understanding of scientific concepts and channel their inquiries into active and meaningful learning experiences. Set includes 221 K'NEX parts – enough to build 7 fully-functioning replicas of real-world machines, one at a time. Supports 2 – 3 students working as a team. Grades 3 -5. Building instructions and comprehensive teacher's guide aligned to Science, Technology, Engineering and Math Standards included. Packaged in a strong storage tray with snap-on lid. STEM Education focuses on science, technology, engineering and mathematics concepts taught through problem-solving, discovery, exploratory learning and critical thinking. STEM Education requires students to be active participants in the learning. K'NEX models offer hands-on learning opportunities that encourage scientific inquiry, investigation and experimentation. Our inquiry-based lessons challenge students as they build, investigate, problem solve, discuss, and evaluate scientific and design principles in action. Aligned to Science, Technology, Engineering, and Math standards.
